Matches in DBpedia 2014 for { ?s ?p Wirephoto or telephotography is the sending of pictures by telegraph or telephone.Western Union transmitted its first halftone photograph in 1921. AT&T followed in 1924, and RCA sent a Radiophoto in 1926. The Associated Press began its Wirephoto service in 1935, and held a trademark on the term AP Wirephoto between 1963 and 2004. The first AP photo sent by wire depicted the crash of a small plane in New York's Adirondack Mountains.Technologically and commercially, the wirephoto was the successor to Ernest A. Hummel's Telediagraph of 1895, which had transmitted electrically scanned schellac-on-foil originals over a dedicated circuit connecting the New York Herald and the Chicago Times Herald, the St. Louis Republic, the Boston Herald, and the Philadelphia Inquirer.Édouard Belin's Belinograph of 1913, which scanned using a photocell and transmitted over ordinary phone lines, formed the basis for the AT&T Wirephoto service. In Europe, services similar to a wirephoto were called a Belino.The first wirephoto systems were slow and did not reproduce well. In 1929, Dr. Vladimir Zworykin, an electronic engineer working for Western Electric, came up with a system that produced a better reproduction and could transmit a full page in approximately one minute.In the 1930s, wirephoto machines of any reasonable speed were very large and expensive and required a dedicated phone line. News media firms like the Associated Press, used expensive leased telephone lines to transmit wirephotos. In the mid-1930s a technology battle began for less expensive portable wirephoto equipment that could transmit photos over standard phone lines. A prototype device in the experimental stage was available in San Francisco when the large Navy air ship Macon crashed in the Pacific off of the coast of California. A photo was taken and transmitted to New York over regular phone lines. Later a totally portable wirephoto copier and transmitter was put into use by International News Photos, which could be carried anywhere and needed only a standard long distance phone line.. }
